help obd emissions test
Hello I wanetd to ask you for some help.
I live in mexico city and currently have a 2012 1m.
I have the following mods:
Cobb Fmic
Cobb charge pipe
Cobb catted downpipes
Cobb accesport V3 with custome PTF stage 2 tune
Maddad midpipes
Akra rear section
In the recent months the city has now established emission inspections via OBD port.
I have read several therads on the n54 emissions tests etc and how to pass them but im not 100% clear and thus wanted to ask for some help or pointers.
To try and get ready for the inspection so far I have scanned my car with the cobb accesport (had a couple of codes and cleared them), then I proceded to buy an autozone obd car doctor device to scan the car. To my surprise it threw this two codes . P0420 P0430, I have read both this codes are associated with catless donpipes. (mine are catted) .
To be sure I am doing things correct. I now need to flash my car back to stock tune, then erase all codes and proced to record a drive cycle.
myq uestiosn are:
1.-How do I knowo the drive cycle is completed?
2.-The codes I have now P0420 P0430 can be due to the car currently not having recorded the drive cycle? or with the stock tune they should go away?
3.-Do I need to buy and install a DP fix even though my downpieps are catted?
Again thank you for your help
regards
diego garcia
